named drawing once again. After that, a backup file is always updated while you
executing the command SAVE or SAVEAS.
You can use RECOVER command to check and attempt to open a damage file.
Then uses AUDIT command to find and correct errors.
To open a damaged file: File > Drawing Utilities> Recover
Command line> RECOVER
-In the dialog box at Files of Type, choose the type of file you
want to recover.
-Choose the directory containing the damaged file.
-Choose the damaged file you want to recover and Click the Open
button or Double click on the drawing you want to open.

To check errors for a drawing file: File > Drawing Utilities> Audit Command line> Audit
1. To choose from the opened drawing, click on File > Drawing Utilities > Audit
2. Input Y or N to determine whether to recover the errors that are automatically found by GstarCAD, and then press Enter.
3.4.2. Drawing Recovery Manager
Once terminated by hardware problems, power failure or software problems, the application is capable of backup the opened
drawing file. At the next startup, the program starts "Drawing Recovery Manager" in which all of the auto-backup drawing files
that have been closed accidentally will be displayed. You can open the file of your demand by double clicking at the Backup
File list on the "Drawing Recovery", if there is any damage to the file, system attempts to recover the drawing in process of
backup.
When program or system stopped by accident, the drawing files need to recover are sorted into the following types.
-Recovered drawing file saved when program fails (DWG)
-Temporary saved file (sv$)
-Backup file (BAK)
-Source drawing file (DWG)

3.5. Manage Drawings
In GstarCAD the Sheet Set Manager allows you to manage the entire project
drawing sheetsets. It can manage all the work flow from sheets creation,
printing and publishing.etc.
In Sheet Set Manager, a sheet set is an organized collection of sheets from
several drawing files and each sheet in a sheet set is a layout in a drawing
file.
Begin taking advantage of sheet set functionality for your current projects with
minimal effort by importing your current drawing layouts into a sheet set. You can easily open drawings from a central location
while you continue edit them using traditional tools.
3.5.1. Sheet Set Control
Lists menu options to create a new sheet set, open an existing
sheet set, or switch between open sheet sets
Details or Preview: Displays either descriptive information or a
thumbnail preview of the currently selected item in the tree
view.
Tree View: Displays the contents of the sheet list.

You can use the following actions in the tree view:
Right-click to access shortcut menus of the operations that are relevant to the
currently selected item.
Double-click items to open them. This is a convenient method for opening drawing files from the Sheet List. You can also
double-click items in the tree view to expand or collapse them.
Click one or more items to select them for operations such as opening, publishing, or transmitting.
Move the cursor over a single item to display descriptive information or a thumbnail preview of a selected sheet, view, or
drawing file.
Drag items within the tree view to reorder them.

The confirm tab will give a summary
of the layouts to be added to the set.
After selecting the Next button the new
layout will be added to the sheet set.
Import layouts to the Sheet Set Manager
To add a new sheet from an existing drawing layout, right clickthe title of the sheet set
and selectImport Layout as Sheet. A new pop up box will appear which allows you to
browse for an existing drawing to add a layout.
Tip: If the import box is not checked, the layout is already in the sheet set or the
layout is unable to be imported into the set.
Managing Sheet Set
Moving and Removing Sheets from a set
Once the sheets have been added to the Sheet Set Manger, they can be
dragged and dropped to the order needed. To remove a sheet from the
set, right click and select Remove Sheet.
Chapter 3_ Create, Open, Save, Recover a Drawing and Manage Drawings

Rename and Renumbering Sheets
To rename and renumber a sheet or a subset, right click on the sheet
needed to be changed and select Rename & Renumber.
A pop up box will show up that will allow the number, sheet title and
layout name to be changed.
Adding project information to a sheet set
To add project information to the sheet set, like
project name, project number, and project
description, right click on the sheet set title and
scroll down to the sheet set Properties. A new pop
up box will display that allows the update of project
information.
Tips: Project information in the sheet set can be
used in object such as fields
Creating Subsets in Sheet Set Manager
Creating subsets in Sheet Set Manager is a fast way to organize and find what is
needed in a big drawing set. To create a subset, right click on the sheet set
and then to New Subset.
The Subset Properties box will pop up. Most of the
properties are basic. Select OK.
A new subset is added to the sheet set manager.
Tip: To move a sheet to the new subset, simply click
and drag to the desired subset.
Publishing Sheet Sets
Sheet Set Manager makes it simple to publish a full set or only select sheets of the construction documents. There are two
ways to plot: Publish directly to the plotter/file or use the Publish dialog box.
Chapter 3_ Create, Open, Save, Recover a Drawing and Manage Drawings
31
Publish and Plot directly to the plotter/file
Right click on the sheet set, scroll to Publish,
and then Publish to Plotter.
This method is used to plot and publish
when the page setup is set per layout.
The drawback to using this option is if
someone plots one of the sheets using
the plot command and saved the setup
to the layout, the layout will not publis
h properly.Sheetset can also be package
d and shared through e-transmit.
Publishing using Publish dialog box may not be as fast as Publishing directly to the plotter/file, but there is less
of a chance the document will come out wrong.
You are also able to use Page Setups saved in the
drawing to particular sheets or the full set.
To pull up the dialog box, right click the Sheet Set
title, scroll to Publish, and then to Publish Dialog
Box. The Publish Dialog Box will display.
Now with page setups, Publish Dialog Box can cha
nge the way the document is published. Now we h
ave the options to publish to Plotter named in Pag
e Setup, DWF, DWFx, and PDF.
Selecting the Sheet Set Publish Options allows the
options to change information like default output location
and naming.
Tip: One of the major options I change the most is type. Multi-sheet
file will place the full set in one file and the Single-sheet file will
place each sheet per file.

4. Control the Drawing Views
4.1. Redraw and Regenerate a Drawing
As you work on a drawing, visual elements may remain after the completion of a command. You can remove these elements by
refreshing, or redrawing, the display.
To redraw (refresh) the current window display: View > Redraw Command line> REDRAW
To regenerate the current window: View > Regen Command line> REGEN
Information about drawing entities is stored in a database as floating point values, ensuring a high level of precision.
Sometimes a drawing must be recalculated, or regenerated, from the floating point database to convert those values to the
appropriate screen coordinates.
4.2. Magnify a View (Zoom)
You can use ZOOM command to zoom in or zoom out the
drawing view to meet your need. You can change the
magnification of your drawing at any time. The cursor
changes to a magnifying glass when a zoom tool is active.
Zoom out to reduce the magnification so you can see more
of the drawing, or zoom in to increase the magnification so
you can see a portion of the drawing in greater detail.
Remark: If you are working in a layout viewport and cannot zoom, the layout viewport may be locked. The scale and view do not
change in model space while panning or zooming in a locked layout viewport.
Chapter 4_ Control the Drawing Views
33
4.2.1. Zooming Methods
To zoom, you can use any of the following methods:
-To define the portion of the drawing to zoom, create a window.
-To zoom in real time, use the Zoom Realtime tool on the Standard toolbar.
-If you have a mouse with a wheel, rotate the wheel to zoom in and out.
4.2.2. Zoom to Magnify a Specified Rectangular Area
You can specify a rectangular area defined by two corners to display the objects within that area as large as possibly.
The lower-left corner of the specified area becomes the lower-left corner of the new view.
To zoom in to an area using a window: View > Zoom> Window Command line> ZOOM
-Choose View > Zoom > Window
-Select one corner of the window around the area you want to magnify.
-Specify the opposite corner of the window around the area you want to magnify.
4.2.3. Zoom in Real Time
Realtime option zooms dynamically by moving your pointing device up or
down. By right-clicking, you can display a shortcut menu with additional
viewing options.
To zoom in real time: View > Zoom>Realtime
Command line> RTZOOM
-Choose View > Zoom > Realtime from the main menu.
-Hold the left mouse button, then drag the cursor forward to zoom in and move back to zoom out.
Chapter 4_ Control the Drawing Views
34
4.2.4. Displaying the Previous View of a Drawing
After you zoom in or pan to view a portion of your drawing in greater detail, you may want to zoom back out to see the entire
drawing. On the View > Zoom menu, the Previous tool lets you restore the previous view. Selecting this tool repeatedly steps
back through up to 25 successive zoomed or panned views.
4.2.5. Zooming to a Specific Scale
You can increase or decrease the magnification of your view by a precise scale factor measured relative to the overall size of
the drawing or in relation to the current display. When you change the magnification factor, the portion of the drawing located at
the center of the current viewport remains centered on the screen.
To zoom to a specific scale relative to the current display: View > Zoom>Scale Command line> ZOOM
-Choose View > Zoom > Scale from the main menu.
-On the Zoom toolbar, click the Zoom Scale.
-Type ZOOM in the command line, choose the Scale option, and then press Enter.
-Type the scale factor, followed by an x (such as 2x).
-Press Enter.
4.2.6. Displaying the Entire Drawing
ZOOM Extents option, displays a view that includes all of the objects in the drawing as large as possible. The view can display
the objects on layers that are turned off but do not include objects on frozen layers.
ZOOM All option, displays all of objects within either the user-defined limits or the drawing extents, whichever view is larger.
You can use the Zoom All tool on the zoom toolbar to display an entire drawing. The Zoom Extents tool on the zoom toolbar
displays the drawing to its extents, making the image fill the display to the greatest possible magnification.
Chapter 4_ Control the Drawing Views
35
4.3. Pan and View
You can move the drawing in any direction using the pan command. Panning shifts or slides the view of the drawing
horizontally, vertically, or diagonally. The magnification of the drawing remains the same, as does its orientation in space.
The only change is the portion of the drawing displayed. To pan, you can use any of the following methods:
-For precise panning, specify two points defining the magnitude and direction of the pan. The first point indicates the starting
point of the pan. The second point indicates the amount of pan displacement relative to the first point.
-To pan in real time, use the Pan Realtime tool on the Standard toolbar.
-If you have a mouse with a wheel, press and hold the wheel, and then move the mouse.
To pan in real time: View > Pan>Realtime Command line> PAN
-Choose View > Zoom > Realtime from the main menu.
-Move the cursor in the direction you want to pan.
-To stop panning, press Enter, ESC or choose Exit from the shortcut menu.
To pan using a mouse with a wheel:
-Press and hold the wheel, and then move the mouse in the direction you
want to pan (The MBUTTONPAN system variable controls this feature.)
4.4. Display Multiple Views on Model Space
When you begin a new drawing, it is displayed in a single window. You can view the drawing in a second window, or you can
divide one window into multiple windows. You can also open and display multiple drawings.
4.4.1. Set Model Space Viewports
The viewports created on the Model tab completely fill the drawing area and do not overlap. As you make changes in one
viewport, the others are updated simultaneously. You can do the following operations at the model space viewport:
-Set Snap, Grid, and UCS icon modes; Pan; Zoom; and restore named views.
-Save orientations of UCS with individual
viewports.
-When executing a command, you can draw
from one viewport to another.
-Name a viewport arrangement in order to you
can reuse it on the Model tab or insert it on a
layout tab.
-When you work on 3D models, is helpful
setting up different UCS in individual viewports.
Chapter 4_ Control the Drawing Views
36
4.4.2. Working with Multiple Views of a Single Drawing
You can open and work with several views of the same drawing simultaneously. After you divide a single window into multiple
windows, you can control each window separately. For example, you can zoom or pan in one window without affecting the
display in any of the other windows. As you draw, any changes you make in one window are immediately visible in the others.
And also you can switch from one window to another at any time.
To create multiple views: View > Viewports Command line> VPORTS
-Choose View > Viewports
-In viewports menu, choose 1, 2, 3, or 4 viewports.
-Type h if you want the horizontal orientation, or type v if you want the vertical orientation.
To join two views: View > Viewports> Join Command line> VPORTS
-Choose View > Viewports > Join
-Click anywhere inside the window you want to keep.
-Click anywhere inside the adjacent window you want to join to the first window.
To restore a named window configuration:
-Type -VPORTS system variable at the command line and press ENTER.
-Then type Restore.
-Then type the name of the window configuration you want to restore.
Chapter 4_ Control the Drawing Views

4.4.3. Working with Multiple Drawings
With the multiple document interface, you can open and work on several drawings at one time, you can copy, cut, or paste an
entity from one drawing to another. Each drawing appears in a drawing window, which has the following advantages: You can
see two or more drawings side by side, and you can easily copy entities from one drawing to another. Under the Window menu,
the following three methods that determine how drawings are arranged are provided for user's choice.
-Cascade
-Tile Horizontally
-Tile Vertically
4.4.4. View Manager
With the view manager, you can create, set current, update
layers, edit boundaries, and deletes named views, and switch
quickly between each views, it is helpful to reduce many
unnecessary view adjust operation.
4.5. Specify a 3D View
You can set a 3D view to facilitate verifying the 3D effects of the drawing, constructing
and visualizing 3D models. You can specify a new viewpoint to create new objects or
modify the existing objects.
4.5.1. Set the Viewing Direction
You view three dimensional drawings by setting the viewing direction. The viewing
direction establishes the viewing position, When you view a drawing from the default
viewpoint (0,0,1), you see a plan view of the drawing. You can change the viewing
direction to look at the drawing from a different vantage point or to work on a three
dimensional model from a different orientation.
Chapter 4_ Control the Drawing Views
38
To set a new viewing direction:
View > 3D Views> Viewpoint Presets Command line> DDVPOINT
-Choose View > 3D Views > Viewpoint Presets
-Set viewing angles at absolute to WCS and relative to UCS by moving the position of the
needle according to your preference. Then click OK button.
To display a plan view of the current drawing: View > 3D Views> Plan View Command line> PLAN
-Choose View > 3D Views > Plan View from the main menu.
-It concludes three plan views: Current UCS, World UCS and Named UCS. Choose one what you want.
Chapter 4_ Control the Drawing Views
39
4.5.2. Isometric View
You can define perspective views of a
model to create realistic effects. Select
predefined standard orthographic and
isometric views by name or description.
These views represent commonly used
options: Top, Bottom, Front, Left, Right,
and Back. In addition, you can set views
from isometric options: SW (southwest)
Isometric, SE (southeast) Isometric, NE
(northeast) Isometric, and NW (northwest)
Isometric.
4.5.3. Draw 2D Isometric Views
With Isometric Snap, you can create 2D objects that appear to be 3D solids.
By setting Isometric Snap on the Draft Settings dialog box and turning on Snap and Grid, you can easily align objects along one
of three isometric planes. However, although the isometric drawing looks like 3D, it is actually a 2D representation.
Chapter 4_ Control the Drawing Views
40
4.5.4. Set Isometric Grid and Snap
By aligning along three major axes, isometric drawing simulates a 3D drawing from specified viewpoint. When the snap angle
is set to 0, the axes of the isometric plane are 30 degrees, 90 degrees and 150 degrees. With Isometric Snap on, you can work
on any of three isometric planes, each with a pair of associated axes.
-Left. The left isometric plane defined by a pair of 90- and 150-degrees axes. The snap and grips align along the 90- and
150-degree axes.
-Top. The top isometric plane defined by a pair of 30- and 150-degrees axes. The snap and grips align along the 30- and
150-degrees axes.
-Right. The right isometric plane defined by a pair of 90- and 30-degrees axes. The snap and grips align along the 90- and
30-degrees axes.
In addition to using ISOPLANE command to switch isometric planes, you can also use shortcut key F5 or CTRL+E. specifying
one of the three isometric planes results in Ortho and crosshairs to be aligned along the corresponding isometric axes.
For example, when Ortho is on, the points you specified align along the simulated plane you are working on. Therefore, you can
draw the top plane first, and switch to the left plane to draw another side, and then switch to the right plane to complete the
drawing.
Top plane Left plane Right plane
Chapter 4_ Control the Drawing Views
41
4.5.5. Change a 3D View Dynamically
You can view objects from any viewing direction by holding down mouse or other pointing devices and moving dynamically.
With dynamic viewing, you can display the effects of changing viewpoint while you change the view. You can execute move or
zoom operations as the 3D Orbit is active. When the 3D Orbit is active, you are not allowed to modify objects. GstarCAD
supports more orbit options like Free Orbit, 3D Continuous Orbit, Orbit along the X-axis, Orbit along the Y-axis, Orbit along
Z-orbit and 3D Orbit Center. Additionally users can create two new meshes through DISH and DOME commands. To close 3D
Orbit, press Enter, ESC or choose Exit from the shortcut menu.
4.5.6. Hide Lines or Shade 3D Objects
Hides or shapes for 3D objects in the current drawing, suppresses the display of the objects (partly or entirely) that are located
behind other objects, or generates a simply shaded image displayed in the current view. You can use HIDE command to
remove the hidden lines to verify the current placement of these surfaces. Hiding background lines makes the display much
clearer, but you cannot modify hidden-line or render views.
Chapter 4_ Control the Drawing Views
42
4.5.7. Add Simple Shading to 3D Objects
Although hiding lines can enhance the drawing and clarifies the design, shading produces a more realistic image of your model.
You can modify shaded objects as you normally would. When a shaded object is selected, the wireframe and grips appear on
top of the shading.
4.6. Render
Rendering creates a 2D image based on a 3D scene. It
shades the scene's geometry using the lighting you've set
up, the materials you've applied, and environmental
settings such as background and fog. At a basic level,
you can use the render command to render your model
without applying any materials, adding any lights, or
setting up a scene. You cannot move or adjust this light.
4.6.1. Render Environment
You can use environmental features to set up atmospheric effects or background
images. You can enhance a rendered image by means of atmospheric effects like fog
and depth cueing or by adding a bitmap image as a background. Fog and depth
cueing are actually two extremes of the same effect: a white color is fog, and a black
color is traditional depth cueing. You can use any color in between.
Chapter 4_ Control the Drawing Views
43
4.6.2. Light
Lighting adds the finishing touch to the scene. You can add point lights, spotlights, and distant lights and set the location and
photometric properties of each.
Point Light: A point light radiates light in all directions from
its location and does not target an object.
Spotlights: A spotlight can be directed towards an object.
Distant Lights: Simulates the effect of sunlight and can be
used to show how the shadows cast by a structure affect the
surrounding area.
Light List: Displays a list of type and light name used in
model. Distant lights and the sun do not appear as interface
objects in the model.
4.6.3. Materials
You can add materials to objects in your drawings to provide a realistic effect. In
the context of rendering, materials describe how an object reflects or transmits
light. Within a material, maps can simulate textures, bump effects, reflections,
or refractions.
5. Precision Tools and the Properties of Drawings
5.1. Specify Units, Angles and Scale
Specify the units of measurement you want to use, their format, and other
conventions.
5.1.1. Set the Units Format
You can set the display format of the unit that includes: scientific, decimal,
engineering, architectural and fractional notation. To enter architectural feet
and inches format, you can indicate feet using the prime symbol ('), for
example, 72'3. You do not need to specify inches by entering quotation marks
("). You can set the unit type and precision in the Quick Setup wizard, the
Advanced Setup wizard, or the Units Control dialog box. These settings
control how your coordinate, offset, and distance entries are interpreted, and how coordinates and distances are displayed.
To open drawing units dialog: Format > Units Command line> UNITS
Chapter 5_ Precision Tools and the properties of Drawing
44
5.1.2. Set Angle Conventions
You can specify the location for angle 0 and the
positive direction for the angle measurement:
clockwise or counterclockwise. You can also
specify the format and the number of decimal
fraction.
-Specify the measurement unit and precision:
The units include grad, radian, surveyor's unit and
degree, minute and second.
-Specify where the angle measurement starts from: east, west, south, north or others. For example, to enter a coordinate
relative to the current coordinate for a property line that is 54 feet, 7 inches long with a bearing of 60 degrees north, 12 minutes,
6 seconds east, enter @54'7"<n60d12'6"e.
-Specify the positive direction: counterclockwise or clockwise. The angle 0 can be set to any location.
5.1.3. Setting Scale Factors
Instead of drawing to a particular scale, you draw everything full size in the
program. When you print your drawing, you can assign the scale at which
the drawing is to print. Scale, however, does affect the way a few elements
such as text, arrows, or linetypes print in your drawing. For example, when
you draw text, you need to determine the text size so that when you print it
later at a particular scale, the text height is correct.
After you determine the eventual scale of your finished drawing, you can
calculate the scale factor for the drawing as a ratio of one drawing unit to
the actual scale unit represented by each drawing unit.
The following table shows some standard architectural and engineering
scale ratios and equivalent text heights required to create text that measures
1/8 inch high when you print the drawing at the specified scale.
You can use these scale factors to predetermine the size of your drawing to
make sure that it fits on a specific size paper when you print it. You control
the size of your drawing by the drawing limits. To calculate the drawing
limits to match the size of your paper, multiply the dimensions of your
paper size by your scale factor.
Standard scale ratios and equivalent text heights
Scale Scale factor Text height
1/16" = 1'-0" 192 24"
1/8" = 1'-0" 96 12"
3/16" = 1'-0" 64 8"
1/4" = 1'-0" 48 6"
3/8" = 1'-0" 32 4"
1/2" = 1'-0" 24 3"
3/4" = 1'-0" 16 2"
1" = 1'-0" 12 1.5"
1 1/2" = 1'-0" 8 1"
3" = 1'-0" 4 0.5"
1" = 10' 120 15"
1" = 20' 240 30"
1" = 30' 360 45"
1" = 40' 480 60"
1" = 50' 600 75"
1" = 60' 720 90"
1" = 100' 1200 150"
Chapter 5_ Precision Tools and the properties of Drawing
45
5.2. Drawing Limits
You can specify the drawing limits that form an invisible boundary around your drawing. You can use the drawing limits to make
sure that you do not create a drawing larger than can fit on a specific sheet of paper when printed at a specific scale.
For example, if you plan to print your drawing at 1/8" = 1'-0" (in other words, using a scale factor of 96) on a sheet of paper
measuring 36 inches x 24 inches, you can set drawing limits to 3,264 units wide (that is, 34 x 96) and 2,112 units high (22 x
96), which allows a 1-inch margin around the edges of the printed image.
To set the drawing limits: Format > Drawing limits
Command line> LIMITS
-Choose Format > Drawing Limits
-Specify the x-coordinate and y-coordinate of the upper right
drawing limit and the lower left drawing limit. You can also click
Select to specify the drawing limits by selecting points in the
drawing.
5.3. Grid and Grid Snap
The grid is a rectangular pattern comprised of minor
and major lines extended over the drawing area.
Displaying grids and using grids snap improve the
performance of regenerating. When you turn Snap
mode on, the cursor adheres or snaps to the invisible
grids. Grid and snap settings are effective tools to use
in your drawing to ensure accuracy. In addition, the
cursor can be restricted to move orthogonally only or
guides can display on the screen automatically at
specified polar angle increments.
5.3.1. Change Grid and Snap Spacing
You can turn Grid and Snap on and off and specify their spacing on the
Snap and Grid tab at the Drafting Settings dialog box. Grid spacing does
not have to match snap spacing. A wide grid spacing can be used as a
reference while a closer grid spacing helps you specify points accurately.
Chapter 5_ Precision Tools and the properties of Drawing
46
5.4. Use Object Snaps
Object snaps enable you to quickly select exact geometric points on existing
entities without having to know the exact coordinates of those points. With
object snaps, you can select the endpoint of a line or arc, the center point of a
circle, the intersection of any two entities, or any other geometrically significant
position. You can also use object snaps to draw entities that are tangent or
perpendicular to an existing entity.
5.4.1. Setting Object Snaps
You can set object snaps using any of the following methods:
-Choose Tools > Drafting Settings > Object Snap, and then click one
of the object snap tools.
-On the Object Snap toolbar, click one of the object snap tools.
-On the status bar, right-click on the Object Snap button to choose
Settings.
-Press and hold down the Shift key while right clicking anywhere within
the drawing window to display the object snap shortcut menu, and then
choose the object snap you want to set.
Additionally, you can find an option called Distance from Endpoint. This option allows snap a certain distance from any
endpoint of objects like line, arc, spline, pline, ellipse arc, mline and any other lines. As long as you pass the cursor over an
object from its endpoints, you will see a green snap point at accurate distance.
Another option called Divide Segments allows snap the divided segment points of objects like line, arc, spline, pline, ellipse
arc, mline and any other lines. Before, if you want to find the divide point, first you need to generate the divided points object,
then snap those points to draw. Now as long as you pass the cursor over an object mentioned above, you will see a green snap
point at accurate distance.
Chapter 5_ Precision Tools and the properties of Drawing
47
5.4.2. AutoSnap Tools
The automatic snap tool is a visual aid tool for snapping that help you
see and use object snaps more efficiently. When any object snap is on,
the system displays a marker and a tooltip when you move your cursor
on over a snap point. AutoSnap turns on automatically when an object
snap is on. By default, AutoSnap marker, tooltip and magnet are on.
You can change the settings of AutoSnap on the Options dialog box.
AutoSnap consists of the following snap tools:
-Marker. The object snap location is displayed when the cursor moves
over or near an object. Marker shape is determined by the snap it is
marking.
-Tooltip. Indicates which part of the object you are snapping to in a flag at the cursor location.
-Magnet. Attracts and locks the cursor onto the nearest detected snap points. Provides a visual that is similar to snapping to a
grid.
-Aperture box. Surrounds the crosshairs and defines an area within which, when you move the cursor, system evaluates objects
for object snaps. You can determine the aperture box is displayed or not, and the aperture box size can be changed too.
5.5. Use Polar Tracking and Object Snap Tracking
Auto tracking includes polar tracking and object snap tracking. You can turn them on and off by repressing POLAR and OTRACK
buttons on the Status Bar. When the polar tracking mode is on, the cursor moves along the specified angle. When the object
snap tracking is on, the cursor moves along an alignment path based on the snap point.
5.5.1. Polar Tracking
When polar tracking is turned on, guides display on the screen automatically at the polar
angle increment that you specify. For example, if you draw a line with polar tracking turned
on with angle increment set as 65 degrees, the rubber-banding line displays at 65 degree
increments.
To enable polar tracking and specify the polar angle increment:
1.Do one of the following:
-Choose Tools > Drafting Settings from the main menu.
-On the Object Snap toolbar, click the Object Snap Settings button.
-Type DSETTINGS in the command line and then
press Enter.
Chapter 5_ Precision Tools and the properties of Drawing
48
2.Switch to the Polar Tracking tab.
3.Select the Polar Tracking On checkbox.
4.Do one of the following to specify the polar angle
increments:
-Select an angle from the Increment Angle drop-down list.
-Mark the Additional Angles check box and click New to
define a custom angle increment.
5.Click OK.
Remark: To toggle polar tracking on and off at any time, click the Polar Tracking button on the status bar or press F10.
To draw objects using polar tracking:
-Turn on polar tracking and start a drawing command, such as ARC, CIRCLE, or
LINE. You can also use polar tracking with editing commands, such as COPY and
MOVE.
-As you move your cursor to specify points, notice the dotted polar tracking line
that appears at the tracking angles you specified. Points you specify while the
line is displayed conform to the polar tracking angle.
5.5.2. Object Snap Tracking
Object snap tracking can track along alignment paths that are based on object snap points and display tooltips at the acquired
points. After you acquire a point, horizontal, vertical and polar alignment paths relative to the point are displayed when the
cursor moves over their drawing path. For example, you can specify a point along a path that is based on an object endpoint or
midpoint or an intersection between objects.
You can also use system variable TRACKPATH to control the display of polar and object snap tracking alignment paths.
Chapter 5_ Precision Tools and the properties of Drawing
49
5.6. Use Orthogonal (Ortho Mode)
You can restrict cursor movement to the current horizontal and vertical axes so that you can draw at right angles, or
orthogonally. For example, when the Draw Orthogonal option is enabled, lines are restricted to 0 degrees, 90 degrees, 180
degrees, or 270 degrees. As you draw lines, the rubber banding line follows either the horizontal or vertical axis, depending on
which axis is farthest from the cursor. When you enable the isometric snap and grid, cursor movement is restricted to
orthogonal equivalents within the current isometric plane. Ortho mode and polar tracking cannot be on at the same time.
Turning on Ortho turns off polar tracking.
To fast enable orthogonal drawing:
-Press F8 or press the ORTO button at the status bar
5.7. Working with Linetypes
A linetype is a repeating pattern of dashes, dots, and blank spaces displayed in a line or a curve. You can assign linetypes to
objects by layer, or by specifying the linetype explicitly. And also, you can specify its scale, load more linetypes into the
program from a linetype library file, and create your own custom linetypes.
By default, every drawing has at least three linetypes: CONTINUOUS, BYLAYER, and
BYBLOCK. You cannot rename or delete these linetypes.
Remark: You should not confuse these linetypes with the hardware linetypes provided
by some plotters. Both linetypes of dashes produce the similar effects. However, if you
use both linetypes at the same time, the results can be unpredictable.
5.7.1. Load Linetypes
GstarCAD includes the linetype definition files gcad.lin and gcadiso.lin. If you select gcadiso.lin, you can use ISO pen-width
option when you plot. If you want to know what linetypes are already available, you can display a list of linetypes that are loaded
in the drawing or stored in an LIN (linetype definition) file. Both linetype definition files contain several complex linetypes.
Chapter 5_ Precision Tools and the properties of Drawing
50
5.7.2. Change the Linetype of an Object
You can change the linetype of an object by changing
the linetype of the layer the object is on, reassigning
the object to another layer, or by specifying a linetype
for the object directly.
5.7.3. Set the Current Linetype
By default, all objects are created using the current linetype, which is displayed in the Linetype Control on the Properties
toolbar. To modify this current linetype, you can select a linetype and make it current in the Linetype Manager dialog box. If the
current linetype is BYLAYER, objects are created
using the linetype assigned to the current layer.
If the current linetype is BYBLOCK, objects are
created using CONTINOUS linetype until they are
grouped into a block. When you insert the block, it
acquires the current linetype setting.
To make the linetype current:
Select a linetype from the Linetype Control
pull-down list on the Properties toolbar, which is set
to the current linetype.
5.7.4. Control Linetype Scale
You can set global or individual scales for objects to control the display of linetypes. The Global Scale Factor and Current
Object Scale are displayed in the Linetype Manager. The Global Scale Factor value is stored in the system variable LTSCALE,
which changes the linetype scale globally for new and
existing objects.
The Current Object Scale is stored in the system variable
CELTSCALE, which specifies the linetype scale for new
objects. In a layout, you can use system variable PSLTSCALE
to adjust the linetype scale in different viewports.
Remark: Setting the linetype scale too large or too small may
result in a line pattern looking like a solid line, depending on
what the scale view is or at what scale the drawing is printed.
To set the current individual linetype scale: Format > Linetype Command line> LINETYPE
Chapter 5_ Precision Tools and the properties of Drawing
51
-Choose Format > Linetype
-Click the Show Details button.
-In the Current Object Scale field, type the linetype scale that you want to make current.
-Click OK.
To change the global linetype scale:
-Choose Format > Linetype
-Click the Show Details button.
-In the Global Scale Factor field, type the global linetype scale that you want to change. Then click OK button.
5.8. Working with Layers
Layers are like the transparent overlays you use in manual drafting. You use layers to organize different types of drawing
information. Each object in a drawing exists on a layer. When you draw an object, it is created on the current layer.
5.8.1 Create and Name Layers
You can create an unlimited number of layers in every drawing and use those layers for organizing information. When you
create a new layer, it is initially assigned the color white (or black, depending on your system settings) and the linetype
CONTINUOUS. By default, a new layer is also visible. After you create and name a layer, you can change its color, linetype,
visibility, and other properties.
To create a new layer: Format > Layer Command line> LAYER
-Choose Format > Layer
-Click the New Layer button.
-Type a name for the new layer and then click
OK button.
To change a layer name in the current
drawing:
-Choose Format > Layer
-In the Layer Properties Manager dialog box, click the name of layer you want to change.
-Type a new name and click OK button.
5.8.2. Setting the Current Layer
When you start a drawing, objects are created
in the current layer. By default, the layer 0 is
set to the current layer, but you can also create
a new one and make it current. Any subsequent
objects you create are associated with the
current layer and use its color and linetype.
Chapter 5_ Precision Tools and the properties of Drawing
52
To make a layer current:
-Choose Format > Layer
-In the Layer Properties Manager dialog box, select a layer and then click the Set Current button to make the layer current.
-Click OK.
5.8.3. Removing Layers
You can remove unused layers from your drawing with PURGE or by deleting the layer from the Layer Properties Manager.
5.8.4. Controlling Layer Visibility
A layer can be visible or invisible. Objects on invisible layers are not displayed and do not print. By controlling layer visibility,
you can turn off unnecessary information.
To turn layers on or off: Format > Layer Command line>
LAYER
-Choose Format > Layer
-Click the icon under "On" tab in the layer list.
-Click OK button.
5.8.5. Locking and Unlocking Layers
Locking a layer prevents you from accidentally modifying its objects. When a layer is locked (but visible and thawed), you
cannot edit them. If you lock the current layer, you can still add new objects to it. You can also change the linetype and color
associated with a locked layer. Unlocking a layer restores full
editing capabilities.
To lock or unlock layers: Format > Layer Command line>
LAYER
-Choose Format > Layer from the main menu.
-Click the icon under "Lock" tab in the layer list.
-Click OK button.
Chapter 5_ Precision Tools and the properties of Drawing
53
5.8.6. Controlling Layer Printing
Controlling layer printing is another way you can specify which objects print in your drawing. By controlling layer printing, you
can turn off unnecessary information during printing. When you turn off printing for a layer, objects drawn on that layer are still
visible, but they do not print.
To turn layer printing on or off: Format > Layer
Command line> LAYER
-Choose Format > Layer
-Click the icon under "Plot" tab in the layer list.
-Click OK button.
5.8.7. Setting a Layer's Print Style
If your drawing uses named print style tables, you can specify a print style for each layer. Named print style tables contain print
styles that you set up to control what objects look like when they print, without actually changing the objects in the drawing. If
your drawing uses color-dependent print style tables, you cannot specify a print style for a layer. These types of print style
tables automatically determine printing requirements by the color assigned to a layer or an object.
To change the print style assigned to one or more layers (only in a drawing that uses named print style tables):
Format > Layer Command line> LAYER
-Choose Format > Layer
-Click the name of Plot Style in the layer list to open Select Plot
Style dialog box, from which, you can specify the desired plot style.
-Click OK button.
5.8.8. Freeze or Thaw Layers
You can also freeze layers to improve the performance of operations such as zooming and panning or producing hidden lines or
shaded images. When a layer is frozen, objects drawn on that layer are no longer visible.
To freeze or thaw layers: Format > Layer
Command line> LAYER
-Choose Format > Layer
-Click the icon under "Freeze" tab in the layer list.
-Click OK button.
Chapter 5_ Precision Tools and the properties of Drawing
54
5.8.9. Setting the Layer Color
Each layer in a drawing is assigned a color. GstarCAD uses the BYLAYER color as the default color setting for object creation so
that new objects are drawn in the color of the layer on which they
are inserted.
To change the layer color: Format > Layer
Command line> LAYER
-Choose Format > Layer
-Click the icon under "Color" tab in the layer list to open Select
Color dialog box, from which, you can specify the desired color
through index, true and color books tabs –Then click OK button.
5.8.10. Setting a Layer's Linetype
Each layer uses a default linetype. Linetype determines the appearance of objects both on the screen and when printed. It's
recommendable to assign the BYLAYER linetype to any objects that you draw on that layer.
To change the linetype assigned to one or
more layers: Format > Layer
Command line> LAYER
-Choose Format > Layer
-Click the Linetype name in the layer list to
open Select Linetype dialog box, from
which, you can specify the desired linetype.
-Click OK button.
5.8.11. Setting a Layer's Lineweight
Each layer uses a default lineweight. Lineweights determine the thickness of objects both on the screen and when printed. All
new layers are assigned the DEFAULT lineweight, which is .25 millimeters or .01 inches. If you want a different lineweight
assigned to a layer, you can easily change it using Layer Properties Manager.
To change the lineweight assigned to one or more layers:
Format > Layer Command line> LAYER
-Choose Format > Layer
-Click the Lineweight name in the layer list to open Lineweight dialog box, from
which, you can specify the desired lineweight.
-Click OK button.
Chapter 5_ Precision Tools and the properties of Drawing
55
5.8.12. Filter List of Layers
You can use a layer filter to limit the display of layer names in the
Layer Properties Manager. The following properties can be included in
the filter definition: Layer names, colors, linetypes, lineweights, and
plot styles. Whether layers are locked or unlocked, turned on or off,
frozen or thawed in the current viewport or all viewports. When setting
filter conditions, you can also use wild-card characters to filter names
by name. For example, typing D* displays layer name preceded with
D, just click Add button if the filter name has been specified.
To filter list of layers:
-Choose Format > Layer
-Click the New Property Filter icon, located at top left of the window.
–In the Layer Filter Properties dialog box, under filter definition, click the tabs properties you want to filter. Then click OK.
5.9. Displaying Lineweights
Lineweights are displayed differently in paper space layout than model space. Lineweights are useful for graphical
representations of different objects and information.
5.9.1. Display Lineweights in Model Space
In model space, a 0-value lineweight is displayed as a pixel, and other lineweights are display with a pixel width proportional to
their real-unit value. In model space, lineweight display does not change with the zoom factor. A lineweight value that is
represented by a width of several pixels is always displayed using the same number of pixels. In model space, press LWT
button on the status toolbar to turn lineweight display on and off.
Chapter 5_ Precision Tools and the properties of Drawing
56
5.9.2. Display Lineweights in Layouts
In paper space (layout tab), lineweights are displayed in exact plotting width. In plot preview and paper space, lineweights are
displayed in real-world units, and lineweight changes with the scale factor. From the Plotting Scale tab of Plot dialog box, you
can control the lineweight plotting and scaling in a drawing. In paper space, press LWT button on the status toolbar to turn
lineweight display on and off. This change does not affect the lineweight plotting.
5.10. Spell Command
Users can check the spelling of all text as it is entered in your drawing with Spell command. Users can also specify the
specific language dictionary that is used and customize and manage multiple custom spelling dictionaries.

6. Create Objects
Drawings are made up of objects. In general, you draw objects by specifying points with the pointing device or by entering
coordinate values at the command prompt.
6.1. Draw Linear Objects
6.1.1. Lines: A line consists of two points: a start point and an endpoint. You can connect a series of lines, but each line
segment is considered a separate line object. To draw a line: Draw > Line Command line> LINE
1.Choose Draw > Line from the main menu.
2.Specify the start point.
3.Complete the first line segment by specifying the endpoint.
4.Press Enter to complete the command.

2.Move the cursor to the end of the line you drew last and then move it back as far
along the line as you want to erase.
3.To end the erasure and return to the sketch Command prompt, enter E. If you want
to change the current viewport while sketching, make sure the pen is up and all lines
were written into the drawing.
6.2. Draw Curved Objects
6.2.1. Arcs: An arc is a portion of a circle. There are numerous ways to define an arc, the
default method uses three pick points, a start point, a second point and an end point. Using
this method, the arc will start at the first pick point, pass through the second point and end
at the third point. Once you have mastered the default method try some others:
-3 points -Start, Center, End -Start, Center, Angle
-Start, Center, Length -Start, End, Angle -Start, End, Direction
-Start, End, Radius -Center, Start, End
-Center, Start, Angle
-Center, Start, Length -Continue
To draw an arc by 3 points as sample:

6.2.5. Helix : Creates a 2D spiral or 3D spring. Initially, the default base radius is set
to 1. During a drawing session, the default value for the base radius is always the
previously entered base radius value for any solid primitive or helix. The base radius
and top radius cannot both be set to 0.
To draw a helix: Draw > Helix Command line>HELIX
The following prompts are displayed: Number of turns = 3 (default) Twist = CCW (default)
1.Specify center point of base: Specify a point
2.Specify base radius or [Diameter] <1.0000>: Specify a base radius, enter d to specify the diameter, or press ENTER to
specify the default base radius value
3.Specify top radius or [Diameter] <1.0000>: Specify a top radius, enter d to specify the diameter, or press ENTER to
specify the default top radius value
4.Specify helix height or [Axis endpoint/Turns/turn Height/tWist] <1.0000>: Specify a helix height, or enter an option
6.2.6. Donut : Donuts are solid, filled circles or rings created as closed, wide polyline. The system variable FILLMODE controls
whether to fill the donut or not. FILLMODE is set to 1, creates filled donuts; if FILLMODE is set to 0, creates without filled.
To create a donut, you specify its inside and outside diameters and its center. You can continue creating multiple copies with
the same diameter by specifying different center points. To create solid-filled circles, just assign the same value for the inside
radius and outside radius.
To draw a donut: Draw > Donut Command line>DONUT
1.Choose Draw > Donut from the main menu.
2.Specify the inside diameter of the donut.
3.Specify the outside diameter of the donut.

6.3. Create 3D Objects
With 3D models, you can: View entities in three dimensions, create three-dimensional entities, edit entities in
three-dimensional space, edit three-dimensional solids, display hidden-line and shaded views of three-dimensional entities.
6.3.1. 3D Thickness and Elevation: By default, the program creates new two dimensional objects with a zero elevation and
thickness. The easiest way to create a three dimensional object is to change the elevation or thickness property of an existing
two dimensional object. You can extrude any two dimensional object into a three dimensional object by changing the thickness
of the object to a nonzero value. For example, a circle becomes a cylinder, a
line becomes a three dimensional plane, and a rectangle becomes a box.
To set the current elevation: Command line>CHANGE
1.Type CHANGE on the command line, and then press Enter after selecting
the two dimensional object(s).
2.Enter P (Properties) and press Enter.
3.Enter E (Elev) and press Enter.
4.Specify a new elevation, and then press Enter.
To set the current thickness:
Command line>CHANGE
1.Type CHANGE on the command line, and then press
Enter after selecting the two dimensional object(s).
2.Enter P (Properties) and press Enter.
3.Enter T (Thickness) and press Enter.
4.Specify a new Thickness, and then press Enter.
6.3.2. 3D Faces: You can create a three
dimensional face, which consists of a section of
a plane in three dimensional space. After you
specify the fourth point, the program continues
to prompt you for additional faces by alternating
prompts for the third point and fourth point to
allow you to build a complex three dimensional
object.
To create a three dimensional face: Draw > Modeling>Meshes>3D Face Command line>3DFACE
1.Type 3Dface on the command line.
2.Specify the first point of the three-dimensional face.
3.Specify the second, third, and fourth points.

Chapter 7_ Modify Objects
79
7.16. 1.Trim and Extend Filleted Objects: While performing fillet, you can
select Trim option to decide whether the selected edges are extended to the
endpoints of fillet arcs. By default, all objects except of circles, ellipses,
closed polylines and splines are trimmed or extended when performing
filleting.
7.16. 2.Fillet Line and Polyline Combinations: If the objects to fillet are a
line and a polyline, the line or its extension must be intersecting with one of
the polyline segments. With Trim option on, the filleted objects join with the
filleted arc to form a new polyline.
7.16. 3. Fillet Parallel Lines: You can fillet parallel lines, rays, and infinite lines.
The first entity must be a line or ray, the second entity can be a line, ray, or infinite
line. The diameter of the fillet arc is always equal to the distance between the
parallel entities. The current fillet radius is ignored.
7.16. 4.Invert Fillet: Invert Fillet has a very wide range of usage particularly
in construction and furniture industry. The FILLET command now offers a
new option called Invert. You can create a reverse fillet by this option.
7.17. Disassociate Compound Objects: You can convert a complex entity,
such as a block or polyline, from a single entity into its component parts. Exploding a polyline, rectangle, donut, polygon,
dimension, or leader reduces it to a collection of individual line and arc entities that you can then modify individually. Blocks
are converted to the individual entities, possibly including other, nested blocks that composed the original entity.
With the following exceptions, exploding an entity usually has no visible effect on a drawing:
Chapter 7_ Modify Objects
80
-If the original polyline had a width, the width information is lost when you explode it.
-If you explode a block containing attributes, the attributes are lost, but the original attribute definitions are retained.
-Colors, linetypes, lineweights, and print styles assigned BYBLOCK may be different after exploding an entity, because they will
adopt the default color, linetype, lineweight, and print style until inserted into another block.
7.18. Modify Polylines: Objects such as rectangles, polygons, and donuts, as well as three dimensional objects such as
pyramids, cylinders, and spheres, are all editable polylines. To modify a polyline, perform PEDIT command. The available
options vary depending on whether the selected polyline is a two dimensional or three dimensional object. If the selected
object is not a polyline, the Edit Polyline tool provides the option of turning it into one. You can convert only arcs and lines into
polylines. If several arcs or lines are joined endpoint to endpoint, they can all be selected and turned into one polyline.
7.19. Modify Multilines: You can use the methods such as common editing commands, a multiline editing command and
multiline styles to edit multilines or their elements. You can use MLEDIT command to add or delete vertices for a multiline, to
control the way two multilines intersected (cross and T shape that can be closed, open or merged), to add multiline style or set
multilines from the existing multiline style, such as the number of elements, color, linetype, lineweight and the offset of each
element.

Chapter 9_ Dimensions and Tolerances
86
9. Dimensions and Tolerances
Dimensions indicate the measurement values of objects (e.g. length or width),
distance or angles among objects, or the distance between feature point and the
specified origin. You can create five basic types of dimensions: linear, angular, radial,
diametral and ordinate. Dimensions have several distinct elements: dimension text,
dimension lines, arrowheads, and extension lines.
1.Dimension text: A character string that usually indicates the measurement value, includes prefixes, suffixes, tolerances, etc.
2.Dimension line: Indicates the direction and extent of a dimension. For linear dimensions, it displays as a line, for angular
dimensions, it displays as an arc segment.
3.Arrowhead: Usually displayed at both end of the dimension line. You can specify various sizes and shapes for arrowheads or
tick marks. 4.Extension lines:
Extend from the object to the dimension line, in order to define dimension ranges.
9.1. Create Dimensions
You can create dimensions by selecting the entity to dimension and specifying the dimension line location, or by specifying the
extension line origins and the dimension line location.
9.1.1. Horizontal and Vertical Dimensions: As you create linear dimensions, the system automatically applies a horizontal or
vertical dimension depending on the specified extension line origins or the
location where you select an object. However, you can create a dimension by
specifying it be horizontal or vertical.
To create a horizontal or vertical dimension:
1.Choose Dimension > Linear from the main menu.
2.Press Enter, and then select the object to dimension. Or, you can specify the
first and second extension line origins.
3.Specify the dimension line location.
9.1.2. Create Aligned Dimensions: In the aligned dimensions, the dimension line is parallel to the line passing through the
extension line origins. The aligned dimension is also parallel to the objects you specify. The system creates the extension lines
automatically.
To create an aligned dimension:
1.Choose Dimension > Aligned from the main menu.
2.Press Enter, and then select the object to dimension. Or, you can specify the
first and second extension line origins.
3.Specify the dimension line location.

9.2.12. Display Lateral Tolerances: Lateral tolerance represents a value that the amount a measured distance can vary. You can
control the degree of accuracy needed for a future by specifying tolerances in manufacturing. These dimension tolerances
indicate the largest and smallest permissible size. You can also apply geometric tolerances to indicate deviations of form,
profile, location, orientation, and runout.
Chapter 9_ Dimensions and Tolerances
94
Deviation tolerances represent with the plus and minus values that are appended to the dimension values. If the deviation
tolerances are equal, the ± signs precede them and they are known as symmetrical. Otherwise, the plus value locates above
the minus value.
The vertical placement of tolerance values that is relative to the main dimension text can be specified. For example, you can
align the tolerances with the top, middle, or bottom of the dimension text.
9.2.13. Set the Scale for Dimensions: Setting dimension scale depends on the method you use to lay out and plot drawings.
Dimension scale has effects on the size of dimension geometry relative to the objects in the drawing. In addition to text height
and arrowhead size, dimension scale affects offsets in dimension as well, such as the extension line origin offset. When you
create dimensions, it's recommended to set the size and offset to values that represent their actual plotted size. However, the
tolerances, measured lengths, coordinates, and angles cannot be applied to the overall scale factor. The method of creating
dimensions in a drawing layout is shown as follows:
-Dimension in model space for plotting in model space. If you want to create dimensions that are scaled correctly for plotting,
you have to set the system variable DIMSCALE to the inverse of the desired plot scale. For example, if the plot scale is 1/4, you
have to set DIMSCALE to 4.
-Dimension in model space for plotting in paper space. If you want to create dimensions that are scaled automatically for
display in a paper space layout, you have to set the DIMSCALE to 0. This method is useful when you encounter the following
situations: the dimensions in a drawing need to be referenced by other drawings (xrefs); when you create isometric dimensions
in 3D isometric views. To prevent the dimensions in one layout viewport from being displayed in other layout viewports, it's
recommended to create a dimensioning layer for each layout viewport that is frozen in all other layout viewports.
-Dimension in layouts. You can create dimensions in paper space by selecting model space objects or by specifying object
snap locations on model space objects. The dimensions created in a paper space layout do not need additional scaling: there is
no need to change the default value of DIMLFAC and DIMSCALE.

95
9.3. Modify Existing Dimensions
You can modify all components of the existing dimension objects in a drawing either individually or by using dimension styles.
9.3.1. Modify Dimension Style:
You can modify all of properties of the
existing dimension objects in a drawing
using dimension styles. You can also create
a dimension style override to temporarily
change a dimensioning system variable
without changing the current dimension
style. If a dimension style is changed, the
dimension associated with that dimension
style updates automatically.
9.3.2. Make Dimensions Oblique: Extension lines are normally created at a
perpendicular angle to the dimension line. You can change the angle of the
extension lines, however, so that they tilt relative to the dimension line.
To make oblique extension lines:
1.Choose Dimension > Oblique from the main menu.
2.Select the linear dimension, and then press Enter.
3.Type the obliquing angle, and then press Enter.
Remark: To align the oblique angle if you don't know the exact measurement,
use snaps to pick two points on the entity.
9.3.3. Dimension Jogged Linear: The DIMJOGLINE command is
available for adding or removing jog symbol for linear dimensions. The
jog symbol is default to be placed at the center point between first
extension line and text. To relocate jog symbol, you can adjust the
position of dimension text or specify new position to locate jog after
reselecting dimension.
To add a jog to linear dimension:
1.Choose Dimension > Jogged Linear from the main menu.
2.Select a linear dimension.

9.3.4. Dimension Inspection: Dimension inspection is created to transmit the frequency of inspecting the part being
dimensioned, the dimension value and parts tolerance are ensured to be within specified range. Dimension inspection is
composed by a frame and internal text and contains utmost three kinds of information field: inspection tag, dimension value
and inspection rate.
Inspection tag, used for mark the text of dimension inspection is located at the left side within the inspection frame.
Dimension value is the value before adding dimension inspection, which is located at the central part of the inspection
dimension including tolerance, text and measurement value.
Inspection rate is expressed by percentage, which is located at the right side within the inspection frame, indicates required
frequency of the part being created.
To create an inspection dimension:
1.Choose Dimension > Inspect from the main menu.

adjust the space among these paralleled lines with an equal value either default or specified. DIMSPACE command adjust the
space among paralleled linear
or angular dimensions or
overlapped dimensions
automatically in case that the
original space is not equal
values. If you set the space
value to 0 when adjusting space
among dimensions, you can
align selected dimensions at the
dimension line as well.

97
9.4. Add Geometric Tolerances
Geometric tolerances show acceptable deviations of form, profile, orientation, location, and runout of a feature. You add
geometric tolerances in feature control frames. These frames contain all the tolerance information for a single dimension.
Geometric tolerances can be created with or without leader lines, you can create them with TOLERANCE or LEADER
command.
A feature control frame consists of two or more components. The
first feature control frame contains a symbol that represents the
geometric characteristic to which a tolerance is being applied,
for example, location, profile, form, orientation, or runout. Form
tolerances control straightness, flatness, circularity and
cylindricity; profiles control line and surface. In the illustration,
the characteristic is position.
9.4.1. Geometric Tolerance Dialog Box: Specifies the symbols and values for a feature control frame.
1. Geometric Characteristics symbol (menu)
2. Tolerance Zone form (toggle)
3. Tolerance zone value
4. Material condition symbol (menu)
5. Datum reference 1 of 3
6. Datum reference 2 of 3
7. Projected tolerance zone symbol (toogle)
8. Projected tolerance zone value
9. Datum identifier
9.4.2. Geometric Tolerance Symbols: The geometric tolerance symbols and their characteristics are shown in the following.
1. Position (Location)
2. Concentricity or Coaxiality (Location)
3. Symmetry (Location)
4. Parallelism (Orientation)
5. Perpendicularity (Orientation)
6. Angularity (Orientation)
7. Cylindricity (Orientation)

9. Circularity or roundness (Form)
10. Straightness (Form)
11. Profile of a surface (Profile)
12. Profile of a line (Profile)
13. Circular runout (Runout)
14. Total runout (Runout)
Chapter 9_ Dimensions and Tolerances
98
9.4.3. Material Conditions: Depending on control type, you can add a diameter symbol prior to the tolerance value, and
specify a material condition symbol behind this value. You can apply material conditions to features that can vary in size.
9.4.4. Datum Reference Frames: A datum reference consists of values and modifying symbols. A datum is a theoretically
exact geometric reference that measures and verifies a theoretically exact point, axis, or plane. The system provides up to three
datum reference letters and relative symbols followed by the tolerance value.
9.4.5. Projected Tolerance Zones: Projected tolerance zones control the height of the fixed perpendicular part of the extension
area, and control tolerance accuracy by positional tolerances. Before you set the symbol to projected tolerance zones, you set a
height value to specify the minimum projected tolerance zone.
9.4.6. Composite Tolerances: A composite tolerance consists of two tolerances that applied to the same geometric
characteristic of a feature or for features that have different datum requirements. Before you create a dimension and add a
composite tolerance for a drawing, you have to specify the first line of a feature control frame and then choose the same
geometric characteristic symbol for the second line of the feature control frame. The specified geometric symbol compartment
is extended over both lines. Then you can create a second line of tolerance symbols.
To add a geometric tolerance:
1.Choose Dimension > Tolerance from the main menu.
2.In the Geometric Tolerance dialog box, click the first square under Sym and select a symbol to insert.
3.Under Tolerance 1, click the first black box to insert a diameter symbol.

12.In the drawing, specify the location of the feature frame.
Chapter 10_ Blocks, Attribute and Xrefs
99
10. Blocks, Attribute and reference
10.1. Create and Insert Blocks
Usually, blocks are several objects combined into one that you can insert into a drawing and manipulate as a single object.
Blocks can help you better organize your work, quickly create and revise drawings, and reduce drawing file size.
10.1.1.Create Blocks: Usually, blocks are several objects combined
into one that you can insert into a drawing and manipulate as a
single object. A block can consist of visible objects such as lines,
arcs, and circles, as well as visible or invisible data called attributes.
Blocks are stored as part of the drawing file. You can use several
methods to create blocks:
-Combine objects to create a block definition in your current drawing.
-Create a drawing file and later insert it as a block in other drawings.
To create a block for use within a current drawing:
1.Choose Draw>Block> Make from the main menu.
2.In the Block Definition dialog box, enter a block name in the Name
box.
3.Click Pick point button to specify the insertion point for the block in
the drawing area.
4.Click Select objects button to select the objects for the block,
then press Enter after selection. Then click OK button.
10.1.2. Create Nested Blocks: You can define blocks and other blocks as nested blocks so as to simplify the organization of
complicated blocks. With nested blocks, you can build a single block out of several components. But you should notice that
blocks that reference themselves cannot be inserted.
Chapter 10_ Blocks, Attribute and Xrefs
100
10.1.3. Create Drawing Files for Use as Blocks: You can create a block as a separate drawing file that you can insert into
other drawings.
To save a block as a separate drawing file:
1.On the command line, type WBLOCK.
2. Under Source area, choose one of the following:
-Block: Saves existing block object to a separate drawing file.
-Entire drawing: Saves the entire drawing to a separate drawing file.
-Objects: Saves those objects you select to a separate drawing file.
3. Under Destination area, type the name of the drawing file you want to
create and choose the saved path, click OK to save.
10.1.4. Change the Base Point of Drawings to Be Used as Blocks: When inserting a drawing file into another drawing as a
block, by default, system uses the origin (0,0,0) of WCS as the base insertion point. To specify different insertion point, you
can use BASE command. Next time you insert the same block, system uses the new insertion point by default.
10.1.5. Update Changes in the Original Drawing: Once the drawing file has been inserted into another drawing as a block, the
original drawing changes as well. But the block having been inserted will not change. If the block happens to change along with
the original drawing, you should attach it as external reference but not as a block.
10.1.6. Use Paper Space Objects in Blocks: Objects created in paper space are not contained in the block when it is being
inserted into the drawing. You can convert the objects in paper space as block or save as an individual drawing file before
inserting into other drawings.
10.1.7. Insert Blocks: You can insert blocks and other drawings into the current drawing. When you insert a block, it is treated
as a single object. When you insert a drawing, it is added to the current drawing as a block. You can then insert multiple
instances of the block without reloading the original drawing file. If you change the original drawing file, those changes have no
effect on the current drawing unless you redefine the block by reinserting the changed drawing.
To insert a block:
1.Choose Insert > Block from the main menu.

10.1.8. Modify a Block Definition: You can redefine all instances of a block within the current drawing. To redefine a block
that was created in the current drawing, you create a new block using the same name. You can update all the blocks in the
current drawing by redefining the block. If the block was inserted from a separate drawing file that was subsequently updated,
reinsert that block to update all other instances in the current drawing.
To redefine a block in the current drawing:
1.Choose Draw > Block > Make from the main menu.
2.In the Block Definition dialog box, type the name of the
block you want to redefine in the Name box.
3.Click Pick point button to specify a point as the insertion
point for the block in the drawing area.
4.Click Select objects button to select the objects for the
block, and then press Enter after selection.
5.Click OK.
6.Click Yes in the prompt box that displays to redefine the
block in the current drawing.
10.1.9. Remove Block Definitions: Too many block
definitions in a drawing file may affect the drawing
size. To reduce the size of a drawing, you can
remove unused block definitions. Erasing a block
reference from a drawing may delete the block
reference but retain the block definitions in the block
definition table. Using PURGE command can help
removing unused block references from your
drawing in order to reduce the drawing size. You
should erase all references from a block before you
can purge the block definition.

2.Select the attribute definition text to edit.
3.Modify the attribute tag, prompt and default in the Edit
Attribute Definition that displays.
4.Click OK.
10.1.11. Modify Block Attributes: You can use the Block Attribute
Manager to modify attributes in block definitions. For example, you
can modify the following items:
-Attributes of blocks can be displayed after modification.
-Text properties that define how attribute text is displayed in the
drawing.
-Properties that define the layer that the attribute is on and the attribute
line's color, weight, and type
To edit an attribute attached to a block:
1.On the command line, type DDATTE.
2.Select the block to edit. The Edit Attributes dialog box displays all
the attributes attached to the block you select.
3.Edit the attribute values as necessary. Then click OK.

10.1.12. Extract Block Attribute Data: Enter EATTEXT to start Attribute
Extraction if the blocks in the drawing contain attributes. You can extract
block information according to the wizard prompt and generate list so
as to overview the attributes information of the blocks. You can get
guide information from the wizard until you accomplish selecting
drawings, blocks and block attributes.
With the extract block attribute data function, you can easily create list
using drawing data through extracting attribute information and export
to external files.
10.2. Reference Other Drawing Files (Xrefs)
External references provide additional capabilities not available when you insert a drawing as a block. When you attach an
external reference, however, any changes you make to the original drawing file are reflected in the drawings that reference it.
External references are useful for assembling master drawings from component drawings. Use external references to coordinate
your work with others in a group. External references help reduce the drawing file size and ensure that you are always working
with the most recent version of a drawing.
10.2.1. Attach External References: When a drawing is attached to current drawing as external reference, it will be linked to
the drawing, any changes to the referenced drawing may affect the external reference in current drawing. External references are
inserted into the drawing as block definitions and used as single objects, but you should distinguish the external references and
blocks.
To attach an external reference:
1.Choose Insert>External References from the main menu.
2.Click the DWG icon at the top left of the window.
3.In the Select Reference File dialog box, specify the drawing file to attach and then click Open.
4.In the External Reference dialog box, under Reference Type, choose how you want to insert the drawing:
-Attachment: Inserts a copy of the drawing and includes any other drawings references.
-Overlay: Lays a copy of a drawing over your original drawing
5.Make any additional selections and then click OK.
6.If you marked Specify On-screen for any items, follow the prompts to attach the external reference

10.2.2. Control the Properties of Referenced Layers:
You can control the visibility, color, linetype, and
other properties of an xref's layers and make these
changes temporary or permanent. If the VISRETAIN
variable is set to 0, these changes apply only to the
current drawing session. You can also control the
fade display through XDWGFADECTL variable. In
addition you can control Xref layer properties directly
into the Layer Manager Properties dialog box.
10.2.3. Xref Clipping Boundaries: You can control whether to display clipping boundary of xref through setting system
variable XCLIPFRAME. Also you can Clip Xrefs by selecting the option on the menu bar: Modify>Clip>Xref
10.2.4. Nest and Overlay External References: Xrefs can be nested in another xref and attached to current drawing. In the
process of attaching, you can select insertion position, scaling factor and rotation angle for xrefs.
10.2.5. Binding an Xref to a Drawing: To provide a copy of a drawing containing
external references to someone else, you must also provide all the external reference
files. Binding the external references makes them a permanent part of the drawing,
which is similar to inserting a separate drawing as a
block. You can bind external references by doing right
click to the selected Xref file.
10.2.6. Refresh Xrefs: You can refresh the Xref by clicking the refresh button located at
the top of the External Reference Dialog Box.

11.2.1. Attach, Scale, and Detach Raster Images:
Raster images consist of a rectangular grid of small
squares or dots known as pixels. Raster images can
be copied, moved, or clipped as well as a normal
object in the drawing. You can also adjust the
contrast, transparency, image quality and image
frame visibility. Additionally, when inserting raster
images, the file format depends on the content of
the file rather than the extension name. The
following table display all the image file formats
supported:
11.2.2. Attach Raster Images: Use IMAGEATTACH command to select and attach raster images, or bitonal, 8-bit gray, 8-bit
color, or 24-bit color image files to a drawing. The image file can be inserted as blocks as many times as you like once
attached to the current drawing, you can clip the attached raster image and setup its lightness, contrast, fading and
transparency.
To attach a raster image:
1.Choose Insert > Raster Image reference from

otherwise to attach it by its original size. The raster image will be scaled by the
specified factor, the scale factor is used without unit by default.
11.2.4. Detach Raster Images: Raster images can be detached if it no longer needs
to use in the drawing, a specified image detached from the drawing together with its
multiple copies, links and definitions, but the original image file will not be
influenced.
11.2.5. Modify and Manage Raster Images: Controls the properties such as displaying and clipping boundary of raster
images. You can view and manipulate attached raster image and change its saving path in Image Manager. Users can turn
on/off image boundary in current view using IMAGEFRAME command and setting up the values 0 (off) 1(on).

12. Layout, Plot and Publish Drawings
12.1 Create Multiple-View Drawing Layouts
12.1.1. Overview of Layout: A layout represents a plotted page on which one or more model views are displayed. GstarCAD
provides two collateral working environments as Model and Layout tab. You can create thematic models on Model tab. Multiple
slides of the model can be set in Layout tab. Use these general steps to prepare your drawing for printing multiple layouts:
1. On the Model tab, create your drawing.
2. Create a new layout. You can use an existing Layout1 or Layout2 tab, or you can create
a new Layout tab.
3. Create at least one layout viewport on the Layout tab. Use each viewport to help control
which portion of the drawing prints and at what scale.
4. Specify additional settings for the layout, such as the scale of the drawing, print area,
print style tables, and more.
5. Print or plot your drawing.
You can right click on Layout tab and select "New layout" to create a new layout, and also import layout from template.
Options on Shortcut menu are listed:
12.1.2. Work with Model Space and Paper Space: Model space is
generally used for creating and editing drawings. Preparations for
plotting are usually working on paper space for the drawings on
layouts are close to the plotting effects.
Model space is an area in which you create two dimensional and
three dimensional objects based on either the World Coordinate
System (WCS) or a user coordinate system (UCS). The contents of
paper space represent the paper layout of your drawing. In this work
area, you can create and arrange different views of your model similar to the way you arrange detail drawings or orthogonal
views of a model on a sheet of paper.
Layout tab is enabled to make relevant plot settings. Paper space is
provided in each layout option, and you are allowed to create
viewports and specify page setup such as paper size, orientation
and location that can be saved together with the layout.
You can save and name the page setup and apply it to other layouts
when setting pages. You can also create new layouts using existing
layout template file (DWT or DWG).
Click on the Model tab, you can view and edit objects in model
space.
Chapter 12_ Layout, Plot and Publish Drawing
113
12.1.3. Specify Layout Settings: Once created a drawing in Model tab,
you can toggle to Layout tab and setup the layout for plotting, such as
paper size, drawing orientation and so on. You can right click on the
Layout tab to create new layouts or import from template files, and then
click Modify button on the Page Setup Manager dialog box to set the
page.
12.1.4. Select a Paper Size for a Layout: The paper size here refers
to the size of the drawing. When you start Plot dialog box in Layout tab,
you can assign the paper type from pull down list of the Paper Size text
box. The Paper size is directly previewed from the sketch with its size
and units. The available paper types provided in the pull down list are
decided by the current configuration. If you want to configure plotters to
export raster images, you must specify output size by pixels. The paper
size can be customized in the Plotter Configuration Editor.
12.1.5. Determine the Drawing Orientation of a
Layout: The drawing orientation is sorted into
Landscape and Portrait, which decide the plotting
orientation of the drawing to be seen on a paper.
Once specified the drawing orientation, you can
control whether to plot the top or the bottom of the
drawing by selecting Plot Upsize-down option. The
changes setup in Page Setup dialog box are still
saved in layouts. Certain page settings can be
replaced by customized plot settings, but the settings
will not be saved in the layout unless you click Apply
to Layout option.
12.1.6. Adjust the Plot Offset of a Layout: You can offset the geometry on the paper by entering a positive or negative value in
the X and Y Offset boxes. Changing the plotting origin may change the position of drawing on papers. The plot origin locates at
the left lower corner of plotting area with offset value of 0 relative to X and Y direction. Select Center on Paper if the specified
plot area is part of the drawing rather than the whole layout, which changes the position of plot origin.
Plot with origin (10,10) Plot with origin (0,0)
Chapter 12_ Layout, Plot and Publish Drawing
114
12.1.7. Set the Plot Area of a Layout: You can set the area to be plotted in Plot dialog box. When creating new layouts, the
default plot option is drawing limits which means plotting all the objects within the drawing paper. The plot origin is (0,0),
located at the left lower corner of the page. Do the following
methods to select a plot area:
-Layout: Plots all the objects within the drawing paper.
-Window: Set the Plot Scale for a Layout, Plots any portion of
the drawing you specify within the rectangle window. Click the
Window button to use a pointing device to specify opposite
corners of the area to be plotted, and then return to the Plot
dialog box.
-Extents: Plots the portion of the current space of the drawing
that contains objects.
-Display: Plots the contents displayed in current view.
12.1.8. Set the Plot and Lineweight Scale for a Layout: When you specify a scale to output your drawing, you can choose Fit
to Paper to scale the drawing to fit onto the selected paper size. Usually, the objects in model space are displayed at the scale
set in layout viewports. To plot the objects in model space with the scale specified in layouts, you assign the scale to 1:1. Even
if plot scale of layouts is assigned, it's enabled to scale the lineweight at a certain scale. Scaling the lineweight is nothing to do
with the plot scale when plotting drawings, which is mainly used for the lines included in the objects to be plotted.
12.1.9. Move and Copy Layouts: You can right
click on the Layout tab to select Move or Copy
option, on the Move or Copy dialog box, you can
select a layout which you want to place after the
current layout. To Create a Copy of current layout,
you can select a layout and check Create a Copy,
the copied layout will place before the layout you
selected. You should notice that Model tab can't
be moved or copied.
12.1.10. Create Layout from Template: Right click on the Layout tab to select from template option to import DWG or DWT file
directly, using information of existing template to create new layouts. System provides template file with extension name
as .dwt. Layout templates from any drawing templates
can be imported into the current drawing.
To create a new layout from an existing file:
1. Choose Insert>Layout>Layout from Template
2. In the dialog box, select the desired template file, and
then click Open. In the Insert Layout(s) dialog box, select
the layout(s) you want to insert, and then click OK. You
can choose multiple layouts by holding down Ctrl while selecting layout names.
Chapter 12_ Layout, Plot and Publish Drawing
115
12.1.11. Create and Modify Layout Viewports: On a Layout tab, you must create at least one layout viewport to see your
model. Each layout viewport is created as a separate entity that you can move, copy, or delete. Any changes you make in one
layout viewport are immediately visible in the other viewports (if the other layout viewports are displaying that portion of the
drawing). Zooming or panning in the current viewport affects only that viewport.
Create layout viewports:
1. On the command line, type MVIEW.
2. Type F (Fit), or create 2, 3 or 4 viewports by entering 2, 3 or
4 separately, or specify two opposing corners to create a
custom viewport.
3. Choose the viewport arrangement, typing H (Horizontal) or V
(Vertical).
4. Do one of the following:
-To arrange the viewports to fill the current graphic area, type F
(Fit)。
-To fit the viewports within a bounding rectangle, specify the
corners of a rectangle.
You can create a single layout viewport, or you can divide the graphic area into many viewports arranged
[Horizontal/Vertical/Above/Below/Left/Right].
To modify layout viewport properties:
1. Click the border of the layout viewport whose
properties you want to modify.
2. Open the Properties palette through the menu option
"Tools >Palettes>Properties" or "Modify > Properties".
3. In the Properties palette, select Standard Scale, and
then select a new scale from the list. The scale you
choose is applied to the viewport.
Turn Layout Viewports On or Off:
1.Click the desired Layout tab.
2. Type MVIEW and then press Enter.
3. Type ON or OFF.
4. Select the edge of the layout viewport to turn on or off, then press Enter.
Create Non-rectangular layout viewports:
Use Object and Polygonal options of MVIEW to create irregular viewports,
Select Object option to convert objects created in paper space to viewports. While selecting
Polygonal option to draw irregular polylines including arcs and lines which are enabled to
either intersect or three vertexes at least, the polyline will be closed automatically.

12.2.4. Set Drawing Orientation: The drawing orientation determines whether to plot a
drawing portrait or landscape. If you select Landscape, plots the drawing using the length
edge as horizontal. While selecting Portrait to plot the drawing using its minor edge as
horizontal Changing, the drawing orientation just like rotating the paper under the drawing.
Meanwhile, selecting Plot upsize-down to control whether to locate the drawing
upsize-down on paper.
12.2.5. Set Plot Scale: Plot scale of the drawing can be specified directly
from the Scale pull-down list in Plot Scale area of Plot dialog box. You can
also choose User define to set desired plot scale, or choose Fit to Paper to
scale the drawing to fit onto the selected paper size. The plot scale
together with plot unit and drawing unit must be specified before plotting.
For example, if you select the paper size to mm, entering 1 under mm and
10 under Units blank produces a plotted drawing with each plotted unit
represents 10 actual millimeters.
To automatically scale the drawing for printing:
1. If necessary, click the desired Layout tab or the Model tab.
2. Choose File > Plot from the main menu.
3. To scale the drawing to fit on one printed page, in Plot Scale, click Fit to Paper.
4. Select Apply to Layout and click OK.

-Plot in Background. Specifies that the plot is processed in background.
-Plot Object Lineweights. Specifies that lineweights assigned to objects and
layers are plotted.
-Plot with Plot Styles. Plots a drawing with specified plot styles. Plots
lineweights automatically once selecting this option automatically. If you do not
select this option, objects are plotted with their assigned properties and not
with the plot style overrides.
-Plot Paperspace Last. Plots model space geometry first. Paper space geometry
is usually plotted before model space geometry.
-Hide Paperspace Objects. Suppresses the plotting of objects that are located
behind other objects regardless of how it's displayed on screen. This option is
only available in the Layout tabs.
-Plot Stamp on. Horizontally or vertically placed the plot stamp information on a specified corner of drawing. The plot stamp
settings can be saved to log file, also cannot be saved.
-Save Changes to Layout. All the changes you make in the Plot dialog box will be saved to the layout if you click OK.

To preview a drawing before printing:
1. If necessary, click the desired Layout tab or the Model tab.
2. Choose File > Plot Preview from the main menu.
3. Do one of the following:
-To print the drawing, click preview and click Plot on the top
left corner of print preview.
-To return to the drawing, click the off button or press Esc.
12.2.9. Use Plot Styles: Plot styles help you control what your drawing looks like when it is printed. Because plot styles are
saved in plot style tables, which are files located on your computer, you can reuse them to help eliminate the need to
reconfigure your print settings each time you print a drawing. A drawing can use one type of plot style table at a time. There are
two types of plot style tables:
-Color-dependent plot style tables (CTB) contain a collection of plot styles based on each of the 255 index colors available in a
drawing.
-Named plot style tables (STB) contain a collection of plot styles that you define. They can vary
regardless of color.
To assign plot style tables:
1. If necessary, click the desired Layout tab, or click the Model tab.
2. Choose File > Plot from the main menu.
3. Under Plot Style Table (pen assignments), select a plot style table in the one of the following:

Chapter 13_ Create and Edit Dynamic Blocks
121
13. Create and Edit Dynamic Blocks
Dynamic block references contain grips or custom properties that change the way the reference is displayed in the drawing after
it is inserted. Dynamic blocks allow you to insert one block that can change shape, size, or configuration, instead of inserting
one of many static block definitions.
Some dynamic blocks are defined so that geometry within the block can only be edited to certain sizes specified in the block
definition. When you use a grip to edit the block reference, tick marks are displayed at the locations of valid values for the block
reference. If you change a block property value to a value other than one specified in the definition, the parameter will adjust to
the closest valid value.
13.1. Dynamic Block Editor: You can access the Block Editor by typing the edit command or by double-clicking the block
without attribute. The Block Editor ribbon interface will show as below, the black arrows mark the stand for parameters, while
the yellow lighting is the symbol for action. It will pop-up toolbars in a classic interface.
13.1.1. Dynamic Block Editor Tool Panels: Using the tools in this Tool Panel to define, edit and modify dynamic blocks
definitions , makes it very convenient and fast.
Manage
Save or Save as the default block; Create or edit another
block.
Tool
Define, edit or update the block attribute.
Chapter 13_ Create and Edit Dynamic Blocks
122
Parameter
You can add parameters for Dynamic Blocks on this panel.
Action
You can add actions for Dynamic Blocks on this panel.
Parameter Sets
You can add the parameter set on this panel.
Visibility
This panel is specially used for Visibility editing.
Close
It is used to exit the Block Editor. Before exiting, some
commands like save or open etc. might not work.
13.1.2. Parameters: Define custom properties for the dynamic block by specifying positions, distances, and angles for
geometry in the block. You add parameters to a dynamic block definition in the Block Editor. In the Block Editor, parameters
have an appearance similar to dimensions. Parameters define custom properties for the block. Parameters also specify
positions, distances, and angles for geometry in the block reference. When you add a parameter to a dynamic block definition,
the parameter defines one or more custom properties for the block.
A dynamic block definition must contain at least one parameter. When a parameter is added to a dynamic block definition, grips
associated with key points of the parameter are automatically added. You must then add an action to the block definition and
associate the action with a parameter.
Parameters also define and constrain values that affect the dynamic block reference's behavior in a drawing. Some parameters
can have a fixed set of values, minimum and maximum values, or increment values. For example, a linear parameter used in a
window block may have the following fixed set of values: 10, 20, 30, and 40. When the block reference is inserted in a drawing,
you can only change the window to one of these values. Adding a value set to a parameter allows you to limit how the block
reference is manipulated in a drawing.
Point Parameter
Icon:
Command: BParameter→O
Defines an X and Y location in the drawing. A point
parameter can be associated with a move or stretch action.
Linear Parameter
Icon:
Command: BParameter→L
Shows the distance between two anchor points. Constrains
grip movement along a preset angle. A linear parameter can
be associated with a move, stretch, scale or array action.
Chapter 13_ Create and Edit Dynamic Blocks
123
Polar Parameter
Icon:
Command: BParameter→P
Shows the distance between two anchor points and displays
an angle value. You can use both grips and the Properties
palette to change both the distance value and the angle. A
polar parameter can be associated with a move, scale,
stretch, polar stretch, or array action.
XY Parameter
Icon:
Command: BParameter→X
Shows the X and Y distances from the base point of the
parameter. It can be associated with a move, scale, stretch,
or array action.
Rotation Parameter
Icon:
Command: BParameter→R
Defines an angle. The rotation angle can be in any value, or
be defined in a range or a specified value.
Alignment Parameter
Icon:
Command: BParameter→A
Defines an X and Y location and an angle. An alignment
parameter always applies to the entire block and needs no
action associated with it. An alignment parameter allows the
block reference to automatically rotate around a point to
align with another object in the drawing. An alignment
parameter affects the rotation property of the block.
Flip Parameter
Icon:
Command: BParameter→F
A flip parameter flips objects. You can associate a flip
parameter with a flip action.
Visibility Parameter
Icon:
Command: BParameter→V
Controls the visibility of objects in the block. A visibility
parameter always applies to the entire block and needs no
action associated with it. In a drawing, you click the grip to
display a list of visibility states available for the block
reference.
Lookup Parameter
Icon:
Command: BParameter→K
Defines a custom property that you can specify or set to
evaluate a value from a list or table you define. It can be
associated with a single lookup grip. In the block reference,
you click the grip to display a list of available values. You
can associate a lookup parameter with a lookup action.
Base Point Parameter
Icon:
Command: BParameter→B
Defines a base point for the dynamic block reference relative
to the geometry in the block. Cannot be associated with any
actions, but can belong to an action's selection set.
Chapter 13_ Create and Edit Dynamic Blocks
124
13.1.3. Actions: Actions define how the geometry of a dynamic block reference will move or change when the custom
properties of the block reference are manipulated in a drawing.
Move
ICommand: BActionTool→M
A move action causes objects to move a specified distance
and angle such as a point, a linear, a polar, an XY parameter,
etc, moves all objects in a selection set in a/any direction.
Scale
Command: BActionTool→S
A scale action such as a linear, a polar, an XY parameter, and
so on, scales the selected objects in the direction of the
parameter. Users can manipulate the grips in different way
by changing the properties and values in the Properties
palette.
Stretch
Command: BActionTool→T
A stretch action causes objects to move and stretch a
specified distance in a specified location. A stretch action
associated with a point, a linear, a polar, an XY parameter,
etc.
Polar Stretch
Command: BParameter→PIn
A polar stretch action rotates, moves, and stretches objects a
specified angle and distance when the key point on the
associated polar parameter is changed through a grip or the
Properties palette. A polar stretch action can only be applied
to a polar parameter.
Rotate
Command: BActionTool→P
A rotate action is always associated with a rotate parameter.
Selected objects can be rotated freely, or the way the grips
are manipulated is different in the Properties palette.
Flip
Command: BActionTool→F
A flip action is always associated with a flip parameter.
Array
Command: BActionTool→A
An array action is associated with a linear, a polar, an XY
parameter, etc, copies and arrays selected objects in
different way.
Lookup
Command: BActionTool→L
A lookup action can only be associated with a lookup
parameter.
13.1.4. The General Steps of Creating a Dynamic Block Definition: In order to get a Dynamic Block Definition, improve block
editing efficiency and avoid repeating modifications, we can create Dynamic Block by the following steps.
Step1: Planning
Before creating Dynamic Block, it is
essential to plan Dynamic Block, plan
the functions, appearance, the method
of drawing and required Parameter(s)
and Action(s) which are needed to
achieve prospective functions.
Step2: Draw geometric figure
The included basic pixel during
Dynamic drawing, of course, you can
draw these pixel in Block Editor.
Step3: Add Parameter and Action
This is the most pivotal step when
creating Dynamic Block. When editing
the Parameter and Action, you not
only consider the achievement of
Parameter and Action, but also
consider the readability of Dynamic
Block and the convenience of
Modification, let the action point of
the Parameter attach on the
corresponding pixel as far as possible,
and put the Action near to its relevant
parameter, if there are more
Parameters and Actions, they still
need to be renamed for understanding,
editing and Modification.
Step4: Test Dynamic Block
Save and Exit Block Editor, start the
Dynamic Block test to check if it
reaches to the prospective effect.
Chapter 13_ Create and Edit Dynamic Blocks
125
13.2. Dynamic Blocks Creation Samples
See what you are able to do within the Dynamic Block Editor, and get the most out of your design. See the follow samples:
13.2.1. Base Point Parameter: Although the majority of parameters only taken into effect when operations are matched with
actions, there are exceptions, base point parameter is one of them.
1. Define blocks: Define block and draw a circle in the block editor, as shown.
2. Add base point: Click "base point" parameter on the parameter panel, put the parameter on
the center of the circle according to system prompt, as shown in the below illustration.
3. Insert block: Save and exit block editor, insert the block in the model. You
can realize, base point becomes the insert point of the block after adding the
base point parameter. Please note, if you set an insert point via the block define
dialog box, and add a base point parameter as well, the base point is the default
insert point.
13.2.2. Visibility: Using the Visibility Parameter function, you can control the display and hide a certain view in Dynamic
Block.
1. Prepare view: Prepare a three cars view and define as block.
Chapter 13_ Create and Edit Dynamic Blocks
126
2. Add Parameter of Visibility: Enter into Block Editor by Double-clicking the Block or right- click the menu, click the button
Visibility of Parameter in the Parameter panel, appoint the position of the Parameter according to the system prompt, as shown
below.
3. Edit the states of Visibility: Double click the button Visibility, the
Visibility States dialog box will be displayed. In the dialog box, you can
rename, new and remove the Visibility States. In order to control the
visibility of the three cars view in this example, we click on new for the
three Visibility States as shown in the following picture.
Click the following button as shown in the picture and choose roadster
in the pull down menu.
Click the “Invisibility” button in the Visibility tool panel, select truck and car, make them
invisible in the “roadster” state, as shown in the following picture, after selecting, press
enter to confirm. For the state of “Car” and “Truck”, set them in the same way.
4. Move and Adjust: After finishing the editing of the Visibility States, move the three cars
view to make them overlap as shown in the picture bellow.
Chapter 13_ Create and Edit Dynamic Blocks
127
5. Test Dynamic Block: Insert the edited Dynamic Block into a drawing, select Dynamic Block and click the grip of Visibility
Parameter, choose one item in the pop-up pull-down list, Dynamic Block will change the display state automatically, as shown
in the following picture.
13.2.3. Alignment: Alignment Parameter can give dynamic blocks the function of alignment automatically, which can save the
step of rotating the blocks.
1. Add an alignment parameter for a roughness symbol: Draw a roughness symbol in the Block Editor.
Select the icon of the alignment parameter. Specify the location and the aligned orientation of the
parameter following what the computer asked as shown in the picture, the dotted line is the align
orientation.
2. Test the dynamic block: Insert the roughness dynamic
blocks, move the align grips, the symbol will align with the
interface of the dimensions, as shown pin the picture
below.
Flip: When you use the "roughness symbol block" to label the spare parts, the symbol is sometimes already in the right position,
however, the characters' direction is not right. We need to add the "character flip" function to receive the correct label.
1. Add flip parameter: Click the "flip" parameter button, add the flip parameter
according to prompt, as shown in the picture.
Chapter 13_ Create and Edit Dynamic Blocks
128
2. Add flip action: Click the flip action button on the action panel, match parameter and object for the action. Herein, we choose
"roughness" as the object, and position the action button, as shown in below picture.
Use the same method to add a
pair of flip parameter and action
of the vertical direction, as
shown:
13.2.4. Point Movement:
1. Draw a drawing: Draw a drawing and define it as a block.
2. Add point parameter: Click point parameter on the tool bar, define the parameter
position according to prompt, as shown in the picture.
3. Add move action: Click move action button on action
panel, match parameter and object for the action, and
define the position. The position of action label does not
affect the effect of the dynamic block, however, for the
sake of beauty& convenience, try to put the label near the
related parameter.
4. Test dynamic block: Insert the dynamic block, drag the blue grip, then move the
keyway to the right accordingly, as shown in below picture. Obviously, the dynamic
block can achieve the expected results. Please pay attention, if it is not run with ortho
constraint, the keyway can move towards every direction because the direction of the
point parameter is random, the
characteristic of the parameter
decides the characteristic of
action.
Chapter 13_ Create and Edit Dynamic Blocks
129
13.2.5. Linear Movement: Actually, limited to the demand of the material mechanics characteristics, keyway is only allowed to
be placed on the central line. So, a horizontal movement is enough for keyway and the movement to other direction is not
meaningful. Next we will take advantage of the linear parameter to define the keyway’s movement direction on the central line of
the step shaft.
1. Draw: Draw the follow drawing and define it as a block.
2. Add linear parameter: The way of adding a linear parameter is similar to
dimension, both try to put the absorption point of the parameter on the central
line of the step shaft.
3. Add Move Action: Different from the point move, after specifying the
parameter, the system will prompt: Specify parameter that is related to
movement. Select right grip of parameter as “Related parameter point”, as
shown in the following picture.
The parameter point we mentioned corresponds to the operate point of Move.
After exiting Block Editor you can drag this point to make dynamic block
change correspondingly. After selecting the related parameter point you can
specify the move objects for action, as shown in the following picture. Place
action label, save and exit dynamic block.
4 .Testing Dynamic Block: Select dynamic block and drag the right grip of the
parameter. Meanwhile, no matter how the cursor moves, the keyway is limited to
the central line of the step shaft. That is to say with the limitation of the linear
parameter, the dynamic block can only move along the direction specified by the
linear parameter.
13.2.6. Number of Grips: In the Block Editor, select the
linear parameters, change the number of grips to “1” in
the properties panel.
Save and exit the Block Editor, choose the Dynamic Block, you will
find that one grip has disappeared. In fact, after changing the number
of grips from “2” to “1”, the first thing that disappeared was the basic
grip of parameters, namely the first point when adding parameters.
Chapter 13_ Create and Edit Dynamic Blocks
130
13.2.7. Angle Offset: Open Block Editor, choose the Angle
offset from 0°to 30°in the action property, save and exit the
block editor
Select the Dynamic Block and then move the right side grip. You will find it
can only move in the direction of 30°as it is shown in the follow picture. The
direction of action can change according to the Angle Offset.
13.2.8. Linear Stretch: During a mechanical design, we often need to change the position as well as the dimension of the
keyway. In this section, we will add Linear Tensile function for the keyway on the step shaft.
1. Add linear parameter:
2. Add stretch action: Click the stretch action button on the action
panel, choose parameter according to prompt and define right
grip as key parameter point, as shown in below picture. The black
object is the operational object of the action, the broken line
frame is the stretch frame, objects intersect with stretch frame will
be stretched, objects which will be selected by the stretch frame
will move.
3. Test dynamic block: Exit from block editor, drag stretch grip to stretch
the keyway, as shown in the picture.
13.2.9. Parameter Value Set: For mechanical designs, we often need to stretch the keyway to a certain length. Now, let us see
how to realize an accurate stretch. Pick linear parameter in block editor, click entry frame which is on the right side of" distance
type" on the Properties panel, a drop-down menu will pop up.
Therein, none is the default option, which means it
can stretch optionally. With the other two options,
you can define the maximum and minimum number
respectively.
Chapter 13_ Create and Edit Dynamic Blocks
131
"Increment" means stretch increasingly, a Value set appears as shown
below after selecting increment. If you choose "list", a Value set appears
as shown in below picture, the dynamic block can only be stretched
according to the number in the list.
Click the text frame which is on the right side of the
"distance value list", one button with ellipsis on it will
appear. Click this button, a "Add distance" dialog box will
be displayed. Add three numbers “1”.“1.5”.“2” in the
dialogue box, as shown in below picture.
Exit from block editor and stretch the right grip, you will see
several gray lines appearing on the right side of the keyway,
and the keyway can only be stretched to the gray line
position, as shown in below picture. Obviously, by value list, you can define certain numbers of the stretch, to realize an
accurate stretch.
13.2.10. Symmetrical Stretch: There is an easy way to realize the two-way stretch which is adding two actions of stretch.
Though it can realize a two-way stretch, the action of stretch is independent. The parameter needs some additional setup to
realize the two-way symmetrical stretch.
-First, add two stretch actions for parameter, and select the two grips
of the two parameters as the relevant point of each action.
-Second, in the misc, modify the base location from "Start Point" to
"Mid Point", like shown in the picture below. Save and exit the block
editor.
For the convenience of watching the effect, we drew a vertical center line in the middle of
the keyway, and then stretched the grip to the left side of the keyway or the right side, as
shown in the picture below. As the grips are moving, the two-way symmetrical stretch is
realized.
13.2.11. Distance Multiplier: Take the step shaft as an example, if we stretch the left part
of the step shaft and the keyway still is at the center point of the smaller diameter shaft
after stretching. Then, we use the “Distance Multiplier” property of action to achieve the
aim.
Chapter 13_ Create and Edit Dynamic Blocks
132
1. Add linear parameter and stretch action for step shaft:
Hide the right grip of the parameter point, the action stretch
box is as in the following picture, the bolded object is the
action operation object.
2. Add Move Action for keyway: Select the left grip of the linear
parameter when moving, stretching the related parameter points.
Move the objects of action and select the whole keyway, as in
the following picture.
3. Modify distance multiplier of action: Select Move
Action and modify the default value from 1 to 0.5 in the
property of the distance multiplier, save and exit the block
editor.
4.Test Dynamic Block: Stretch leftwards grip and with the grip moving leftwards,
the smaller diameter shaft will appear with a stretch effect, the keyway will also
move leftwards accordingly, meanwhile, the keyway is in the center of the
smaller diameter shaft of the step shaft all the time. Although Stretch and Move
have a common parameter, when the Distance Multiplier of Move is modified to
0.5, the displacement of Move can only stretch 0.5 times of the displacement.
13.2.12. Chain Action: If you want to realize a symmetric stretch without changing the keyway center and the length of smaller
diameter shaft changes with the stretch at the same time, how can you realize that?
1. Add stretch for Step Shaft: Add stretch parameter and action for step
shaft as the following picture shows. There into, the bolded objects
indicate the operation object of action. Because the follow-up operation
will not stretch the step shaft by grips of this linear parameter, the grip’s
number of the linear parameter can be modified to “0”.
2. Add linear parameter for keyways: Set the base point
position of the line parameter as “Center” in order to
realize the symmetric stretch function.
3.Add the stretch rightwards action for the keyway and
realize chain action: Select the “Distance” linear
Chapter 13_ Create and Edit Dynamic Blocks
133
parameter and modify the chain action of prosperity from “NO” to “Yes” as the following picture shows:
Add the Stretch Leftwards action for keyway as the following picture shows.
Special Note: Do elect “Distance” for the linear parameter to stretch
leftwards the operation objects set. This is a necessary procedure of the
chain operation.
4.Test Dynamic Block: After dragging the left grip, not only the keyway will
stretch bi-directionally and symmetrically but also the smaller diameter shaft of
the step shaft will stretch automatically. This is a chain action. The realization of
a chain action has two important procedures: First, modify the property value of
the parameter that need to happen as linkage and modify the property of “chain
action” from “NO” to “YES”. Second, elect the parameter of objects that are
elected to linkage action to set.
13.2.13. Scale Action: Scale Action can be matched with the Linear Parameter, Polar and XY Parameter to achieve various
Dynamic effects.
Linear Scale
1. Draw: Finish drawing an access hole in a model space and define it as a block, as shown in the
following picture.
2. Add Linear Parameter: Enter into Block Editor to add a
linear parameter. The start point of the Linear Parameter is
the center of the circle, and choose the number of grip as
“1”as shown in the following picture.
Chapter 13_ Create and Edit Dynamic Blocks
134
3. Add Action: Click the Scale icon on the Action Panel, appoint
parameter for Action and box the whole access hole as Action Object,
as shown in the following picture.
4. Test Dynamic Block: Exit from Block Editor and insert the Dynamic block,
after pitching up the Dynamic Block, drag the triangle grip, the objects (nuts)
will scale with it.
Polar Scale
When we move the Scale Grip of the Access Hole on the left of circle center, namely move the
base point of the Linear Parameter to the left of the circle center, we will find that the block does
not have a corresponding Scale, as shown in the following picture.
The reason for this is that the Endpoint of the Linear Parameter cannot cross its base point, so
we change the Linear Parameter to be a Polar Parameter, we do not change any other
operations, as shown in the following picture.
Exit from Block Editor, Drag the grips of the Access hole Block again,
you can see, that after the change from Linear Parameter to Polar
Parameter, we can drag the grip to scale the dynamic block in any
direction.
13.2.14. Scale Character: In this section, we will explain some Scale characters using XY Parameter and Scale Action in a
paired example.
1. Drawing graphics: Draw the graphics which need a dynamic block and define them as a block as below:
2. Add XY Parameter: Entry Block Editor, add XY Parameter. Parameter adding is similar to Linear Parameter. Pick the first point
Chapter 13_ Create and Edit Dynamic Blocks
135
of the parameter from the left bottom corner of the rectangle as the base point, the second point from the top right corner and
change the Number of Grips to “1”. Then add Scale Action, as shown below.
3. Test the Dynamic Block: After exiting the Block Editor, drag the grip of the top right
corner of the rectangle, you can see the whole dynamic block is scaling as the grip is
moving. It is easy to find that both the circle and the rectangle scale by the base point
of the XY Parameter.
5. Modify Action Base: Modify Base type: go back to Editor, select Scale Action and change the default “Dependent” to
“Independent”.
Specify new base: Single click the right input box of “Base-X” and
“Base-Y”, you can manually input the coordinate value or you can
single click the small button with ellipsis dots on the right of the
input box and snap the base point, as shown:
Specify the base point by crosshair and the circle center as base point. After
exiting Block Editor, scale the dynamic block. After modifying Base type and
position, the scale center of the dynamic block changes from the XY Parameter
base point to the new specified base point (center of the circle).
Chapter 13_ Create and Edit Dynamic Blocks
136
6. Scale Type: There is “Scale Type” in the Scale Action
Properties. The default value is “XY Scale”. If you choose
“XY Scale”, the dynamic block scales whenever the scale
grip moves to X axis or Y axis. If you choose “X Scale”, it
scales only when the grip of the scale moves to X axis.
Same, when you choose “Y Scale”.
13.2.15. Rotation: In this section, we are going to use a rotation parameter and rotate action to add a dynamic rotate function to
view index symbols (English system) which are frequently used in architectural drawings.
1. Draw a drawing: Draw a view index symbol and define as a block, as shown in below picture. Please
define view number and drawing number as attribute text, so as to revise whenever you want.
2. Add rotation parameter: Pick the center of the circle as the first point of the parameter, system default it as the rotation point,
set angle type as "increment", and define its number as 15 degree, as shown below.
3. Add rotate action: Click the rotation action
button on the action panel, match parameter,
object and position for the action and select the
whole index symbol as the object of the action.
4. Test dynamic block: Exit from block editor and insert the block, drag
rotation grip to reach the effect of rotation, as shown in below picture.
13.2.16. Polar Stretch: We use the Polar Stretch function of Dynamic Blocks to draw the section symbol in this section.
1. Draw, Mirror and Define as a Block: The follow drawing includes the attribute text which can be modified as you need. Then
mirror this drawing and define the mirrored object as a block.
Chapter 13_ Create and Edit Dynamic Blocks
137
2. Add action and parameter for the attribute text: Add Point
Parameter and Move Action for text and change the Chain
Action to “Yes” .It is ready for next step to create Chain
Action for Polar Stretch Action.
3. Add Polar Parameter and Action: Add Polar Parameter whose first point
should be the center of the section symbol. This point will be the rotation center
of the Polar Parameter. Follow the instructions below:
1. Pick the right grip of the Polar Parameter as an associated parameter point and specify the Stretch box (Fig. 3.1).
2. Select objects to stretch and the “position” Point Parameter together, which can accomplish that the text and section symbol
are moving together (Fig. 3.2).
3. Specify objects which rotate only for Polar Stretch Action (Fig 3.3).
4. Specify Action symbol location (Fig 3.4)
5. Repeat the above steps to add the same parameter and action order for the left part.
Fig 3.1 Fig 3.2
Fig 3.3 Fig 3.4
It is better if you hide the grips which are not associated with the Polar Stretch Parameter as below:
4. Test Dynamic Block:
Chapter 13_ Create and Edit Dynamic Blocks
138
Open the graphic which needs to be dimensioned
and insert the completed dynamic block (Fig 4.1).
Drag the grip of the dynamic block, the section
symbol can be stretched outward and rotated
around the center, and you finish the section
symbol mark (Fig 4.2).
Fig 4.1 Fig 4.2
13.2.17. Polar Stretch Action Characteristics: Modify the grips’ number of the polar
parameter in the section symbol dynamic block in the last example to display both of
the two grips of the polar parameter. From the following picture we can see that the
central grip is clearly different before and after. Before modifying, the central point was
actually the base point of the block, and this was the insert point. But after modifying,
the center point of block is the base point of the polar parameter.
Clicking central grip can move the grip to any direction. Meanwhile, the dark blue insert point of block will appear again, as
shown in the following picture. Obviously, the insert point is only covered by the base point of the polar parameter. The base
point of the polar parameter can move arbitrarily, but for the block it seems that no
change is happening. But is it true?
In order to confirm if the block changes or not, we move the grips on
both terminals and we can find that the section symbol does not center
on the dark blue base point when changing but it takes the base point of
the polar parameter as a rotate center, as shown in the following picture.
Enter block editor, move up the parameter and the other settings do not change.
Exit block editor, move the right grip and you can see that rotate center moves up along with the parameter. From the examples
above it is difficult to understand that the polar parameter cannot move arbitrarily like the point parameter and linear parameter,
the reason is that the base point of the polar parameter
specifies the rotate center of the object, once the parameter is
moved, the rotate center will move accordingly. That the rotate
parameter cannot move arbitrarily has the same reason.
Chapter 13_ Create and Edit Dynamic Blocks
139
13.2.18. Array: For the Array function of Dynamic Block we need to use Array Action, we use Array Action to match with Linear
Parameter, Polar Parameter, XY Parameter to achieve various Arrays.
Linear Array
1. Draw: Draw a parts list and define it as a block.
2. Add Linear Parameter: After adding Array Action, we can drag the two grips of the Parameter to make a list array, but
obviously, we hope just to achieve an up array of the blank bar, not a down array, so to avoid a mistakes, we should hide the
grip under the Parameter, as in the following picture.
3. Add Array Action: During the add Array Action, the system will require to appoint space between columns. The space
between columns is the distance between the objects that the array created. Here, the line width is 7mm, for the line between
the lines a close up array can be chosen, we appoint that the space between the columns is 7mm.
4. Test Dynamic Block: Insert Dynamic Block, drag the top right corner grip upwards, the line number of the part list will be
added automatically, as in the following picture.
XY Array
Compared with Linear Array, XY Array
has a vertical direction Array.
Chapter 13_ Create and Edit Dynamic Blocks
140
Polar Array
We see a Dynamic Block example as follows, after
dragging grip, the effect will be as in the following
picture. You can see, not only can we stretch the fence,
but we can also rotate the direction casually, this is the
effect combining Polar Stretch with Polar Array.
Enter into Block Editor, Stretch, the ways of adding Array
Action as in the following picture, the bold object expresses
the relevance with the selected action. The Polar Parameter
determines the way of Array directly, the Polar Array will regard
the direction of the Polar Parameter as Array direction,
achieving Array functions in any direction.
